Solve -5+2n> -11 or -6-10n> 44

-5+2n>-11

2n>-6 (+5 to both sides)

n>-3 (divide 2 to both sides)

-6-10n>44

-10n>50 (+6 to both sides)

n<-5 (divide -10 to both sides)

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
